Line protection MCCB with TM210 release and undervoltage coil
The breaking capacity is 52.5 kA at 240 V AC, 32 kA at 415 V AC, 13.6 kA at 440 V AC, and 7.5 kA at 690 V AC — so the interrupting rating drops as system voltage rises, which matters when coordinating downstream protection on a 480 V or 690 V bus.
Above that, the datasheet specifies a derating curve: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C.
Physical dimensions and panel fit
The 3VA1080-2ED32-0CH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint for this SENTRON frame — it occupies three 25.4 mm module positions on a DIN rail or panel-mount base. Depth of 70 mm includes the body but not the handle projection; verify clearance for the undervoltage release wiring and auxiliary contact terminations.
